海洋資源枯竭是全球性的議題，維持及復育海洋多樣性是迫切且有效的解決方案。本98年度計畫針對青灣內灣棲地復育可行性作初步研究，結果顯示經過3個月後，1126株移植無性生殖分枝剩下545株，存活率為48.4％；366塊回收的珊瑚附著板上，其中56片有76個可辨識的珊瑚苗，早期幼生死亡率高。 目前青灣內灣正面臨結螺侵襲，結螺族群密度為22.4/ m2，比2003年高出4倍。攝食偏好試驗顯示結螺會選擇美麗軸孔珊瑚為食。可能攝食結螺的物種，10種實驗物種當中，鋸緣青蟹表現出攝食結螺成體的情況，而且攝食效率高。 青灣內灣珊瑚造礁功能群物種幼苗數量少、死亡率高，殘留的珊瑚亦正遭受到嚴重的劣化壓力，抵抗性跟恢復性的潛力低，後續棲地復育及保育是迫切的重點工作。

研究報告摘要(英) Depletions of fishery resources are global issues. The maintenance and recovery of marine biodiversity are possible remedies or solutions to the crisis. Studies on the degraded habitat recovery in Chinwan Inner Bay (CIB) were conducted in 2009. Preliminary results of this project showed that the survival rate of the transplanted asexual colonies of Acropora spp. is 48.4% (545/1126). As for the settlement plate retrievals, there were 76 coral spats on 56 plates but most of them were dead, which meant coral juveniles were facing very high early mortalities. The coral communities in CIB were seriously grazed by the outbreak of Drupella spp. The density of the Drupella snails were 22.4/ m2, which was four-fold higher than the one in 2003. Acropora muricata was preferred prey for the snails. Among 10 of the possible candidates of biological-control predators of Drupella snails, only mud crab, Scylla serrata, showed highly efficient feeding abilities. The amount of new recruits of functional groups for reef-building is low and they suffer from very high early mortalities. Remained colonies of corals in CIB are also facing very high degrading pressures. Potentials of resistance and resilience are low. Therefore, recoveries and conservations of habitats are urgent tasks in the following years
